Abstract (en)
[origin: EP0102340A2] 1. Method of constructing reinforced concrete works such as road tunnels, underground galleries, tunnels for underground railways, according to which an open trench is first excavated, in which there are then placed, consecutively and contiguously, prefabricated hollow concrete elements (4) each consisting of a frame, and a filling is finally executed, characterised in that there is used for each prefabricated element a frame, the external faces of which comprise reinforcements (5), that a filler concrete (18) is poured covering the joints between elements and cooperating with the reinforced concrete of the elements (4) and with the reinforcements (5) so as to construct by consecutive stages, and rapidly, a monolithic work, the strength of which is appreciably greater than the respective strengths of the prefabricated elements (4) initially placed and of the filler concrete (18).
